What kind of doctor treats Eye Allergies?

An ophthalmologist, a doctor who treats eye disease, can treat eye allergies. An allergist, a doctor who finds and treats allergy triggers, can also help. A direct primary care or concierge doctor can be a first stop for an evaluation and can refer you to a specialist when needed.

What are eye allergies?

Eye allergies are also called allergic conjunctivitis. The conjunctiva is a clear layer of tissue that lines the eyelids and covers the white of the eye.

The conjunctiva becomes swollen or inflamed when you react to pollen, dust mites, pet dander, mold, or other allergy-causing substances. Allergic conjunctivitis is the most common allergy that affects the eyes.

Eye allergies can be seasonal or perennial. Seasonal means they come at certain times of the year. Perennial means they last all year. The seasonal type is much more common.

Symptoms

Eye allergy symptoms may be seasonal and can include:

  • Intense itching or burning eyes.
  • Red eyes.
  • Puffy eyelids, most often in the morning.
  • Tearing, or watery eyes.
  • Stringy eye discharge.

Eye allergies are often seasonal and can come with nose and throat symptoms.

In severe cases, there can be more inflammation. This can rarely affect your vision.

Causes and who gets it

An allergen is something that causes allergies. When your eyes meet an allergen, your body releases a substance called histamine. Histamine makes the blood vessels in the conjunctiva swell. The eyes can become red, itchy, and teary very quickly.

Pollens from grasses, ragweed, and trees can cause symptoms. The seasonal type is linked to airborne allergens such as pollen or molds. The year-round type is usually triggered by dust mites, animal dander, or molds.

Allergies tend to run in families. Long-term swelling of the outer lining of the eyes can happen in people with chronic allergies or asthma. This is called vernal conjunctivitis. It is most common in young males and most often happens in spring and summer.

How doctors diagnose it

The diagnosis is based on your history, your signs and symptoms, and an eye exam. Your provider may look for small, raised bumps on the inside of the eyelids.

Allergy testing may find the pollen or other substance that triggers your symptoms. Skin testing is the most common method. It is more likely to be done if symptoms do not respond to treatment.

Doctors also think about other eye problems, such as infectious conjunctivitis, blepharitis, or dry eye.

Treatment

The best treatment is to avoid what causes your allergy symptoms as much as possible. Common triggers to avoid include dust, mold, and pollen.

Some things you can do to ease symptoms are:

  • Use lubricating eye drops.
  • Apply cool compresses to the eyes.
  • Do not smoke, and avoid secondhand smoke.
  • Take over-the-counter oral antihistamines, or use antihistamine or decongestant eye drops.

Antihistamines are medicines that block histamine. These medicines can offer more relief, but they can sometimes make your eyes dry. Do not use the eye drops if you have contact lenses in. Do not use decongestant eye drops for more than 5 days, as rebound congestion can occur.

If home care does not help, you may need to see a provider for eye drops that contain antihistamines or eye drops that reduce swelling. Mild steroid eye drops can be prescribed for more severe reactions. Steroids are medicines that calm swelling. You may also use eye drops that stop a type of white blood cell called mast cells from causing swelling.

A visit to an ophthalmologist should happen before steroid eye drops are used. The eye pressure must be measured, and a more thorough eye exam is needed. Symptoms often go away with treatment. However, they can persist if you keep being exposed to the allergen.

When to see a doctor

Contact your provider if any of these happen:

  • Your symptoms do not respond to self-care steps and over-the-counter treatment.
  • Your vision is affected.
  • You have eye pain that is severe or getting worse.
  • Your eyelids or the skin around your eyes become swollen or red.
  • You have a headache in addition to your other symptoms.

How a direct primary care or concierge doctor fits in

A direct primary care doctor charges a flat monthly fee instead of billing insurance, while a concierge doctor usually charges more and often works alongside insurance. Such a doctor can do an evaluation, follow up on your symptoms, and refer you to an eye doctor or an allergist when needed.

Common questions

What is the difference between seasonal and year-round eye allergies?

Seasonal eye allergies come at certain times of the year, while year-round ones last all year. The seasonal type is related to airborne allergens such as grass, tree, and weed pollens or molds. The year-round type is usually triggered by dust mites, animal dander, or molds.

Do eye allergies go away?

Eye allergies often get better with treatment. However, they can come back if you keep being exposed to the allergen.

Can I use decongestant eye drops every day?

No, you should not use decongestant eye drops for more than 5 days, because rebound congestion can occur. These medicines can also make your eyes dry. Do not use the drops while you have contact lenses in.

Are eye allergies the same as pink eye?

Not always. Allergic conjunctivitis is sometimes called allergic pink eye. Infectious conjunctivitis is a different problem that doctors also think about when they look for the cause.
